    Keywords: Graue Literatur
    Abstract: Nearly one in three children under age five in the Philippines is stunted, a key marker of undernutrition. This rate is high for the country's level of income. This paper provides the first detailed multivariate analysis of potential drivers of stunting in the Philippines, using data from the 2015 National Nutrition Survey. Potential drivers are analyzed individually and grouped in major categories. The analysis finds that stunting between 24-60 months is principally associated with suboptimal prenatal conditions and inadequate food security and diversity. If the results are given a causal interpretation, they imply that if all Filipino newborns had adequate prenatal conditions, the fraction stunted at age 24-60 months would fall by 20 percent. Similarly, providing adequate food security and diversity to all Filipino children would reduce stunting by 22 percent. Other factors - including access to water, sanitation, and environmental conditions - have less strong associations with stunting. The results point to a series of policy priorities to reduce stunting: supporting the nutrition and health of expectant mothers, ensuring access to contraception to reduce adolescent pregnancy, and ensuring that children consume a variety of healthy foods, including protein-dense foods such as milk, meat, and eggs

    Parallel Title: Erscheint auch als Demombynes, Gabriel COVID-19 Age-Mortality Curves are Flatter in Developing Countries
    Keywords: Graue Literatur
    Abstract: A greater share of reported COVID-19 deaths occur at younger ages in low- and middle-income countries (LMICs) compared to high-income countries (HICs). Based on data from 26 countries, people age 70 and older constitute 37 percent of deaths attributed to COVID-19 in LMICs on average, versus 87 percent in HICs. Only part of this difference is accounted for by differences in population age structure. In this paper, COVID-19 mortality rates are calculated for each age group by dividing the number of COVID-19 deaths by the underlying population. The resulting age-mortality curves are flatter in countries with lower incomes. In HICs, the COVID-19 mortality rate for those ages 70-79 is 12.6 times the rate for those ages 50-59. In LMICs, that ratio is just 3.5. With each year of age, the age-specific mortality rate increases by an average of 12.6 percent in HICs versus 7.1 percent in LMICs. This pattern holds overall and separately for men's and women's mortality rates. It reflects some combination of variation across countries in age patterns of infection rates, fatality rates among those infected, and under-attribution of deaths to COVID-19. The findings highlight that experiences with COVID-19 in wealthy countries may not be generalizable to developing countries

    Keywords: 2007 - 2014 ; Arbeitsmarkt ; Bildungsertrag ; Arbeitsmarktstatistik ; Vietnam ; Graue Literatur
    Abstract: This paper uses Labor Force Survey data to assess key aspects of the labor market in Vietnam over 2007-14. The analysis finds large growth in wage employment in the foreign-owned and domestic private sectors. However, the state sector remains a major employer, particularly for workers with higher education, employing 70 percent of wage workers with a university degree. Low-skilled occupations dominate the stock of existing jobs, but the top growing occupations overwhelmingly belong to high-skilled categories. The paper notes that the high unemployment rates of recent university graduates, which have raised concern about a mismatch between skills and employer needs, reflect the transition to the job market and diminish sharply as graduates age. The returns to education in the private sector are highest for university graduates. Finally, women and ethnic minorities are less likely to work in wage jobs, and those that do earn lower wages, although the wage gap for women has declined over time

    Abstract: This paper examines the relationship between narcotics trafficking and violence in Central America. The first part of the paper addresses particular questions posed for the 2011 World Development Report and examines several competing hypothesis on the drivers of crime in Central America. A key finding is that areas exposed to intense narcotics trafficking in Central America suffer from higher homicide rates. Drug trafficking has corrupted state institutions, which have been overwhelmed by the resources deployed by trafficking organizations. The second part of the paper reviews the reasons drug trafficking and anti trafficking enforcement are associated with violence in general and consider policy options

    Abstract: There are several possible explanations for the observed changes in inequality, the returns to education, and the gap between the wages of informal and formal salaried workers in Argentina over the period 1980-2002. Largely due to the lack of evidence for competing explanations, skill-biased technical change is the most likely explanation for the increases in the returns to education that occurred in the 1990s. Using a semi-parametric re-weighting variance decomposition technique and data from the Permanent Household Survey, the authors show that during the same period there was an increase in the returns to unobserved skill. This finding lends support to the hypothesis that skill-biased technical change has been a main driver of increases in inequality in Argentina. The pattern of changes suggests that the growth in returns to unobserved skill may have been partly responsible for the relative deterioration of informal salaried wages during the 1990s

    What has Driven the Decline of Infant Mortality in Kenya? (2012)

    Parallel Title: Gabriel Demombynes What has Driven the Decline of Infant Mortality in Kenya?
    Abstract: Substantial declines in infant and under-5 mortality have taken place in recent years in many countries in Sub-Saharan Africa. Kenya's infant mortality rate has fallen by 7.6 percent per year, the fastest rate of decline among the 20 countries in the region for which recent Demographic and Health Survey data is available. Kenya's rate of postneonatal deaths per 1,000 live births fell by more than half over a five-year period, dropping from 47 to 22, as measured using data from the 2003 and 2008-09 Demographic and Health Surveys. Among the possible causes of the decline are various targeted new public health initiatives and improved access to water and sanitation. A Oaxaca-Blinder decomposition using Demographic and Health Survey data shows that the increased ownership of insecticide-treated bednets in endemic malaria zones explains 39 percent of the decline in postneonatal mortality and 58 percent of the decline in infant mortality. Changes in other observable candidate factors do not explain substantial portions of the decline. The portion of the decline not explained may be associated with generalized trends such as the overall improvement in living standards that has taken place with economic growth. The widespread ownership of insecticide-treated bednets in areas of Kenya where malaria is rare suggests that better targeting of insecticide-treated bednet provision programs could improve the cost-effectiveness of such programs

    Abstract: The authors examine the performance of small area welfare estimation. The method combines census and survey data to produce spatially disaggregated poverty and inequality estimates. To test the method, they compare predicted welfare indicators for a set of target populations with their true values. They construct target populations using actual data from a census of households in a set of rural Mexican communities. They examine estimates along three criteria: accuracy of confidence intervals, bias, and correlation with true values. The authors find that while point estimates are very stable, the precision of the estimates varies with alternative simulation methods. While the original approach of numerical gradient estimation yields standard errors that seem appropriate, some computationally less-intensive simulation procedures yield confidence intervals that are slightly too narrow. The precision of estimates is shown to diminish markedly if unobserved location effects at the village level are not well captured in underlying consumption models. With well specified models there is only slight evidence of bias, but the authors show that bias increases if underlying models fail to capture latent location effects. Correlations between estimated and true welfare at the local level are highest for mean expenditure and poverty measures and lower for inequality measures

    Parallel Title: Demombynes, Gabriel Students and the market for schools in Haiti
    Abstract: Uniquely among Latin American and Caribbean countries, Haiti has a largely non-public education system. Prior to the earthquake of January 2010, just 19 percent of primary school students were enrolled in public schools, with the remainder enrolled in a mix of religious, for-profit, and non-governmental organization-funded schools. This paper examines changes in Haitian schooling patterns in the last century and shows the country experienced tremendous growth in school attainment, driven almost entirely by growth in the private sector. Additionally, it provides evidence that the private market “works” to the extent that primary school fees are higher for schools with characteristics associated with education quality. The paper also analyzes the demand and supply determinants of school attendance and finds that household wealth is a major determinant of attendance. Given these findings, the authors conclude that in the near-term paying school fees for poor students may be an effective approach to expanding schooling access in Haiti

    Parallel Title: Demombynes, Gabriel Kenya's Mobile Revolution and the Promise of Mobile Savings
    Abstract: The mobile revolution has transformed the lives of Kenyans, providing not just communications but also basic financial access in the form of phone-based money transfer and storage, led by the M-PESA system introduced in 2007. Currently, 93 percent of Kenyans are mobile phone users and 73 percent are mobile money customers. Additionally, 23 percent use mobile money at least once a day. New potential for mobile money has come with the rise of interest-earning bank-integrated mobile savings systems, beginning with the launch of the M-KESHO system in March 2010. The authors examine the mobile savings phenomenon, using data collected in a special survey in late 2010. They show that the usage of bank-integrated mobile savings systems like M-KESHO remains limited and largely restricted to better-off Kenyans. However, what the authors term "basic mobile savings"-the use of simple mobile money systems as a repository for funds-is widespread, including among those who are otherwise unlikely to have any savings. Holding other characteristics constant, those who are registered for M-PESA are 32 percent more likely to report having some savings

    Parallel Title: Demombynes, Gabriel Challenges and Opportunities of Mobile Phone-Based Data Collection
    Abstract: The proliferation of mobile phones in developing countries has generated a wave of interest in collecting high-frequency socioeconomic surveys using this technology. This paper considers lessons from one such survey effort in a difficult environment-the South Sudan Experimental Phone Survey, which gathered data on living conditions, access to services, and citizen attitudes via monthly interviews by phones provided to respondents. Non-response, particularly in later rounds of the survey, was a substantial problem, largely due to erratic functioning of the mobile network. However, selection due to non-response does not appear to have markedly affected survey results. Response rates were much higher for respondents who owned their own phones. Both compensation provided to respondents in the form of airtime and the type of phone (solar-charged or traditional) were varied experimentally. The type of phone was uncorrelated with response rates and, contrary to expectation, attrition was slightly higher for those receiving the higher level of compensation. The South Sudan Experimental Phone Survey experience suggests that mobile phones can be a viable means of data collection for some purposes, that calling people on their own phones is preferred to handing out phones, and that careful attention should be given to the potential for selective non-response
